Chemical Research Letters, May 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. In an article, author is Vijayakumar, E. K. S., once mentioned the application of 532-32-1, Name is Sodium benzoate, molecular formula is C7H5NaO2, molecular weight is 144.1032, MDL number is MFCD00012463, category is benzisoxazole. Now introduce a scientific discovery about this category, SDS of cas: 532-32-1.
A gradient reversed phase HPLC method was developed and validated for the analysis of related substances in zonisamide (1,2-benzisoxazole-3-methanesulfonamide), using a Waters Symmetry C8 (150FNx013.9 mm) column with a flow rate of 1.0 ml/min and detection at 280 nm. The mobile phase component A consisted of a mixture of 0.02 M aqueous potassium dihydrogen phosphate-acetonitrile-methanol (75:10:15 v/v/v), pH adjusted to 4.0 with orthophosphoric acid. The mobile phase component B consisted of a mixture of 0.02 M aqueous potassium dihydrogen phosphate-acetonitrile-methanol (15:40:45 v/v/v), pH 2.0 with orthophosphoric acid. The limit of detection and limit of quantitation were in the range of 0.001-0.007 and 0.0035-0.25 respectively with respect to sample concentration of 2 mg/ml. The method was linear in the range of LOQ level to 200 of specified limits for II-VIII (< 0.10, r (2) = 0.9958-0.9999). The method is sensitive, specific, linear, accurate, precise and stability-indicating for the detection and quantitation of precursors (viz., 4-hydroxycoumarin, 1,2-benzisoxazole-3-acetic acid, 1,2-benzisoxazole-3-bromoacetic acid, 1,2-benzisoxazole-3-methylbromide, sodium 1,2-benzisoxazole-3-methanesulfonate), process impurities (viz., 2-hydroxyacetophenone oxime and 3,3,3-tribromomethyl-1,2-benzisoxazole) and drug degradation products formed under stress conditions. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 532-32-1 help many people in the next few years. SDS of cas: 532-32-1.
